Isn't it A= 2 ? 2 with VMs + 2 In maintenance mode + 2 as resiliency (N+2)

IT is C. It states N+2 resiliency as a requirement: 2 hosts for the running load + 2 more. There will remain two hosts: from which one can be put in maintenance mode. while the other host remains available for a failover scenario (because the condition is to have N+2 all the time).

Why can't the customer put both remaining hosts in maintenance mode? The requirement is N+2. They need 2 hosts to run the workload, 2 for failover, that leaves 2 hosts with spare capacity. Imagine customer puts both hosts in maintenance mode, and loses the two production hosts it still leaves 2 hosts to run all the workload. Hence A is the right answer.

well guys this is a tricky question, I think when he said "at the same time" it matter here, we've got : 2Host for VM load, when will put 2 host in the same Time in MM this n+1==> which Mean for n+2 it will Left None

Do they mean the 2 hosts are at full capacity with no room, or do they mean they still provide HA (n+1) ? If the latter, then it would be 3 hosts - 1 to run the VMs and 2 for the N+2, which leaves 3 hosts able to put in MM.
